This Infinity Primus 6004A 4-Channel amplifier is a result of arduous testing and quality control. This amplifier features an input level control adjusts input sensitivity. When low level inputs are used, this control can adjust the input between 200mVrms and 5.0Vrms. When high level inputs are used, the control adjusts the input between 0.5Vrms and 15Vrms. Black with grooved center panel, polished badge, black painted end panels and bottom, this Infinity amplifier will not only enhance your vehicle's sound system, but it will also add a classy, visual flair. The Primus amplifier has on-board circuitry to protect them from shorts, temperature, overvoltage and undervoltage. An LED indicator is included on all four models to let you know when one of these conditions exists. Infinity takes its craft seriously and wants every consumer to have a world-class experience that lasts and lasts!
